METHOD AND PLANT FOR PLATING ON METALLIC STRIP BY IMMERSION INTO MELT Russian patent published in 2009 - IPC C23C2/24 C23C2/40 

FIELD: metallurgy.

SUBSTANCE: invention concerns field of immersion plating into melt. Metallic strip is vertically passed through tank with melt and through located in front of it guide channel, in area of which it is created electromagnetic field by means of two field magnets located from both sides of product for keeping of melt in tanks for strip stabilisation in midposition in guide channel. Electromagnetic excitation of field magnets is changed and/or by means of two located from both sides of strip correcting coil it is created electromagnetic field, overlaid on electromagnetic field of inductors, at that for strip stabilisation in midposition it is measured actuating force in horizontal line, rendered by strip on force sensing element at declination from midposition and depending on measured force is operated on inductive current in field magnets and/or on inductive current in correcting coil. Facility contains tank with melt, located in front of tank guide channel, in area of which from both sides of strip there are provided field magnets for creating of electromagnetic field, and measurement element of actuating force in horizontal line, rendered by strip on force sensing element at declination from midposition in guide channel, and also regulating facilities, which are appropriate for control of inductive current at least in one inductor depending on measured force.

EFFECT: effectiveness increasing of regulation, what provides strip keeping in the middle in guide channel.
